THOMAS SPENCER, OF PUEBLO, COLORADO.

GRASS-ELEVATOR FOR HORSE LAWN-MOWERS.

Specification of Letters Patent.

Application filed. July 22, 1909.

Patented Apr. 5, 1910. Serial No. 509,022.

To all whom it may concern:

Be it known that I, THOMAS SPENCER, a citizen of the United States,residing at the city of Pueblo, in the county of Pueblo and State ofColorado, have invented certain new and useful Improvements inGrass-Elevators for Horse Lawn-Mowers; and I do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to thenumerals of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in grass elevators for horse lawnmowers, in which two slatted belts are driven by the lawn mower gearingthrough a geared connection thereto by means of sprocket wheels andsprocket chain in such manner, that the adjacent surfaces of the slattedbelts move in the same direction, so that the grass thrown up by themower will be held between the belts and conveyed upward and depositedinto a suitable receptacle: and the objects of my invention are: first,toprovide a grass elevator for a lawn mower which receives its powerfrom the moving parts of the lawn mower: and second, to provide a grasselevator that will securely hold the grass from the point where itreceives the grass to the point of delivery into an attached receptacle.I attain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation of a lawn mower with myimprovements attached thereto in position for operation: and Fig. 2 is aside elevation of my invention removed from the lawnmower.

Similar numerals refer to similar parts shown in the drawings.

At the rear of, and near the blades (1) of the cutting drum of a lawnmower, a curved cutting plate (2) is securely attached in such mannerthat grass cut by the blades of the mower will be cast upwardly towardthe point (3) until it arrives at the upper slatted belt (6). The slats(5) which engage the grass at the point 1) and convey it to the lowerslatted belt grass is securely held by the slats of both belts andconveyed upward between them,

and the surfaces of the belts (6) moving up- 6) where the wardly at thesame speed, the grass is conveyed up to the end of the belt carrier anddropped onto the slanted side (21) of the attached receptacle. Thereceptacle is attached by bolts to the casting (18) of the lawn mower bythe bent bar (17 on which the sides and end of the receptacle aresecurely attached, the door (19) being hinged by hinges (20) so they maybe opened outwardly, so as to permit the grass to be cast out of thereceptacle to the ground.

The slatted belts operate over rollers (22) which are carried at thesides of the casting (13) which is secured by bolts through arms (14 tothe housing (15) of the lawn mower. The two lower rollers (22). areidlers over which belts (6) turn; the upper rollers are secured to theirshafts, one shaft having a gear thereon (11) and the other a gear (12),the gears being of the same proportions and meshing together. One ofthese upper shafts carries a sprocket wheel (10) on which sprocket chain(16) operates, the latter receiving power from sprocket wheel (8) whichis secured on the same shaft that carries gear wheel (7), which receivesits power from gear (9) of the lawn mower. Power is thus transmittedfrom the lawn mower to operate the slatted belts (6), which move atequal speeds, gears (11) and (12) being the same s1ze.

Having thus described my inventionso that those who are versed in theart can construct and use the same, I claim:

The combination with a mower having a frame, ground wheels and a gearwheel driven by one of said ground wheels, of a conveyer frame connectedto the mower frame and extending at an angle therefrom, rollers atopposite ends of said conveyer frame, conveyer belts on said rollers,gear wheels on two of said rollers meshing with each other, anintermediate shaft, a gear wheel on said shaft driven by said firstmentioned gear wheel, and means connecting said shaft and one of saidrollers whereby the latter are caused to rotate, and the adjacent faceof the belts caused to travel in the same direction.

In testimony whereof, I affix my signature, in presence of twowitnesses.

THOMAS SPENCER.
